Mix Yield Calculator at 68% target mix yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target mix yield to 68%, then walk the calculation through step by step. Calculate finished-product yield from a concrete, ceramic, glass, or building-products batch.

The inputs for this scenario

  • Saleable output from the mix: 850 pieces (held at the documented default)
  • Theoretical output expected from the batch: 1,000 pieces (held at the documented default)
  • Target mix yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Mix Yield Calculator = saleable output from the mix ÷ theoretical output expected from the batch × 100.
  • Mix Yield Calculator works out to 85 % mix yield at these inputs, and this is the headline figure for the scenario.
  • Mix Yield Calculator gap to target works out to -17 points at these inputs.
  • Saleable output from the mix works out to 850 count at these inputs.
  • Theoretical output expected from the batch works out to 1,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target mix yield sits at 95% and the headline result is 85 % mix yield, this scenario lands almost exactly on the baseline at 85 % mix yield.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target mix yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes your theoretical output is correctly calculated — if the expected count is optimistic or based on an outdated recipe, the yield will look worse than the process actually is.
